The Program Manual
This main part describes the installation of the game, the menu
structure (explaining all options in the setup menu), the tape
recorder, where your levels are stored and how to create your own
level sets.

The Elements Reference
This is a description of most game elements and how they interact
with other elements, grouped by element type. In many cases this is
more helpful than the single element descriptions in the level editor.

The Editor Tutorial
This part describes all editor “drawing” functions and explains how
to edit element properties, including custom elements, which make it
possible to create completely new game elements with unique features.
